WASTE-VALVE IVIECHANISM.

Application filed April 23, 1923.

To @ZZ whom t may concern.'

Be it known that I, Onvrs WV. VALLIER, a citizen of the United States, residing at Vv'atertown, in the county ot Jeiierson and State of New York, have invented certain new and useful Improvements in W aste- Valve Mechanism, of which the following is a specification.

This invention relates to a waste valve mechanism, designed for use in connection with lavatories, baths, and the like, and has for its object to provide a novel and simple mechanism, by which the ordinary popup Stoppers may be reciprocated, for opening and closing the waste outlets. And a further object is to generally improve, sim plify and cheapen the construction and operation of waste valve mechanismspct the class.

I attain these objects by the means set forth in the detailed description which follows, and as illustrated by the accompanying drawing', in which- Figure 1 is a central vertical section through a basin and related parts, to which my improvement is applied. Fig. 2 is a de tached view of the operating plunger and related operating parts. Figz is a detached view of one form of waste stopper.

Fig. 4 is an enlarged fragmentary view ok the plunger and disc. Fig l5 is an edge view of the same. And Fig. 6 is an edge view of the disc.

I-n the drawing, 2 represents an ordinary lavatory, which is supported at 3, and 2' is the waste opening in the bottom of the bowl 2. 4- represents the usual waste bush` ing that extends below and guides the stopper 5, the upper end of the latter being formed with a bevel disc or head, which conforms to an annular seat 11' of the buslr ing. To the lower end of the bushing 4 is.

end being provided with a horizontal slot 5a. The stopper 5 is raised and lowered by means of a rod 7, whose inner end plays in the slot 5, and is bent, as at 7', 1for producing a crank-like movement when the rod is rotated, for reciprocating the Vstopper (see the full and dotted lines in Fig. 1). The rod 7 extends laterally through the arm 6' of the T, and is operatively supported by a bushing 8, whoseinner end screws into n the arm 6", and also by a gland-nut 9, which Serial No. 633,952.

screws into the outer end of the bushing. Intermediate its ends, the rod 7 is formed with a rigid enlargement or sleeve 7a, which is confined between a -shoulder 8' of the bushing, and a washer 10, which prevents longitudinal movement of the rod. Between the nut 9 and the washer 10 is disposed a packing 9', for preventing leakage around the rod. The rod 7 extends beyond the nut 9 a considerable distance, and adjustably supports a disc 12, which is rigidly secured to the rod by a set-screw 12'. The disc proper is form-ed like a spool, having a short barrel 12a, and similar circular end portions 12b12 of larger diameter, which comprise the chines and form a continuous peripheral groove, and the periphery of the barrel is formed with a notch or socket 12d. The disc 12 and the rod 7 are rotated on a horizontal axis, as one part, by a manually operable plunger 13, which is movable vertically in an opening 2a of the basin 2, as well as 1n a relatively long tubular guide ,14, which is encased in and is supported by a sleeve 15. The top end of the plunger is preferably tted with a hand-knob 13', which projects above, andr is normally Supported, by a head 14:' of the tube. The sleeve 15 is held in place by a nut 15', which screws on to the lower threaded end of the tube 14. The lower threaded end of the plunger 13 adjustably supports an inverted L-shaped member 16, the latter having a plane body 16', which has an oval opening 16a, that loosely receives the barrel of the disc 12, while the chines 12"-12c overlap the opposite faces of the body 16', and operatively hold the parts together. vAt one side of the opening 16L is formed an inwardly facing tooth 16h, which normally enA gages the socket 12d of the barrel 12, so

that when the plunger is raised orlowered. the tooth 16b rotates the disc 12 andv shaft 7 (see full and dotted lines in Figs. 1 and l), and correspondingly raises and lowers the stopper 5,l for opening and closing the waste outlet 2'. It will be understood, that the principle upon which the member 16 and the disc 12 operate, is' practically the same as that of the ordinary rack-andpin .ion gearing, wherein the pinion, in the present case, has a liXed axis, while the rack is reciprocated for rotating the pinion.

It is desirable, in a mechanism of the class herein shown and described, when the stopper 5 is raised fordraining the bowl 2, that the said stopper, as well as the plunger 173, and the various connecting parts, shall remain in the operated positions until the time arrives for closing the outlet 2. To this end, the plunger i3 preferably snugly tits the relatively long tube ld to an extent that requires some' force to overcome the it'rictional vengagement ot' said parts. Furthermore, the enlargement 7a ot the rod 7, when properly disposed in the bushing 8, may be subjected to enough tension by the tightening of the nut 9, to prevent the accidental rotation of the rod, and the conse-y quent shifting or lowering ot the stopper and plunger.

rlhe provision oitl the 'lu 6, and the peculiar construction ot the bushing 8 and the rod 7, with which are associated the novel actuating means comprising the disc l2 and its operating member 16, constitute a reliable and smooth-working valve mechanism, which performs its work positively, readily and quietly, and requires little or no attention or care after it is once properly in stalled. The adjustment provided between the plunger 13 and the member 1.6, as well as the means for adjusting the disc lf) relan tively to the rod 7, renders my mechanism readily adaptable to the varying measurements with which plumbers frequently have to contend with, without requiring any altei-ations, or any new parts. Furthermore, the entire absence of the usual loose and noisy parts, renders the present mechanism less liable to become impaired or disordered, than any ot the older waste operating` mechanisms known to me. y Y

l. A waste valve mechanism, including a valve, a crank-rod, operatively connected with said valve, a disc carried Fby said crank-rod having a socket; and a reciprocatable member having an opening to operatively receive said disc and having an inwardly -t'acing tooth engaging said socket for rocking said cranial-od. v
